Cannot use tag names when polling cpppo's server.enip.main server simulation about cpppo HOT 1 CLOSED

Thanks for the efforts you've put in! The API can be a bit hairy; it developed over time, as I discovered more nooks and crannies in EtherNet/IP CIP...

When you use the poll API, if you want to use Tags, make sure you set the 'pass_thru=True' keyword. Otherwise, every parameter processed by the 'parameter_substitution' method is expected to be set up in the parmaters (or self.PARAMETERS) dictionaries. With this set, anything not found will be assumed to be a Tag name, and will be passed thru.

Give that a try, and see if there is anything else.

Also, when you get a None back -- this generally the flag that means that there was an error in reading the target attribute. Unfortunately, you'll need to increase logging to get more details about the failure. If you are using some of the advanced cpppo.server.enip.client APIs that return a large tuple of details about the operation (eg. client.connector.pipeline), then one of the tuple elements will be the CIP status code. However, increasing logging has usually been most useful to me.

Hope that helps!
